Nonprofit tax return filing runs on a 990-series form filed once a year with the IRS, and the version you owe depends on how much money moves through the organization. Most 501(a) groups file some flavor of Form 990 by the 15th day of the 5th month after their accounting year ends. Miss three years in a row and the IRS automatically revokes your exempt status, so choosing the right form and hitting the deadline is the core of staying in good standing.
Which 990 Form Your Organization Owes
Federal law requires most tax-exempt organizations to file an annual return covering gross income, receipts, disbursements, and other information the IRS prescribes.1Office of the Law Revision Counsel. 26 U.S. Code 6033 – Returns by Exempt Organizations Four forms cover almost everyone:
- Form 990-N (e-Postcard). For organizations with gross receipts normally $50,000 or less. It’s a short electronic notice confirming the organization still exists and operates, with minimal financial detail.2Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations — Form 990-N (e-Postcard)
- Form 990-EZ. For organizations with gross receipts under $200,000 and total assets under $500,000. Shorter than the full return but still asks for real financial detail.3Internal Revenue Service. Form 990 Series Which Forms Do Exempt Organizations File Filing Phase In
- Form 990. The full return, required once gross receipts hit $200,000 or total assets hit $500,000. It includes detailed financial statements, governance disclosures, program descriptions, executive compensation, and functional expense classifications.
- Form 990-PF. Every private foundation files this one, no matter how small. It covers investment income, excise taxes, and charitable distributions.4Internal Revenue Service. About Form 990-PF, Return of Private Foundation or Section 4947(a)(1) Trust Treated as a Private Foundation
A handful of exempt organizations file something else entirely: employee benefit trusts file Form 5500, black lung benefit trusts file Form 990-BL, and religious or apostolic organizations described in Section 501(d) file Form 1065.5Internal Revenue Service.

Who Doesn’t Have to File
Churches, their integrated auxiliaries, and conventions or associations of churches are exempt from the Form 990 requirement by statute.6Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations No application is needed; the exemption is automatic.
The line matters, because faith-based organizations that don’t meet the IRS definition of a church still file. A religious education program or a faith-based social service agency, for example, files like any other 501(c)(3). Government entities and certain church-affiliated organizations also fall outside the standard Form 990 filing pool.5Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Overview – Annual Return Filing Exceptions Any organization exempt from the annual information return can still owe a Form 990-T if it earns unrelated business income.
When the Return Is Due
The return is due on the 15th day of the 5th month after the organization’s accounting period ends. Calendar-year filers hit May 15. A June 30 fiscal year produces a November 15 deadline.7Internal Revenue Service. Annual Exempt Organization Return Due Date
Filing Form 8868 on or before the due date buys an automatic six-month extension, no explanation required.8Internal Revenue Service. About Form 8868, Application for Extension of Time To File an Exempt Organization Return A calendar-year filer using the extension has until November 15. One catch: the extension applies to the return itself, not to any tax owed. Organizations with unrelated business income tax still need to estimate and pay by the original due date.
The IRS also postpones filing dates automatically for organizations in areas covered by a FEMA disaster declaration, and it publishes a running list of covered disasters with the adjusted deadlines.9Internal Revenue Service. Tax Relief in Disaster Situations
Late Filing Penalties
Penalties run per day, starting the day after the due date, and they scale with organization size:
- Organizations with gross receipts under $1,208,500 pay $20 per day, capped at the lesser of $12,000 or 5% of gross receipts.10Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Filing Procedures: Late Filing of Annual Returns
- Organizations at or above $1,208,500 in gross receipts pay $120 per day, capped at $60,000.10Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Filing Procedures: Late Filing of Annual Returns
These amounts are adjusted for inflation each year under the underlying statute.11Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc. Penalty abatement for reasonable cause is possible but not freely granted.
The Three-Year Automatic Revocation
The bigger risk isn’t the penalty; it’s losing exempt status altogether. An organization that fails to file its required return or e-Postcard for three consecutive years automatically loses its tax exemption, effective on the due date of the third missed return.12Internal Revenue Service. Automatic Revocation of Exemption Once revoked, the organization owes federal income tax on its earnings, can no longer receive tax-deductible contributions, and drops off the IRS’s Publication 78 database that donors check.
Getting reinstated means filing a new exemption application (Form 1023, 1023-EZ, 1024, or 1024-A) and paying the user fee again. Organizations that apply within 15 months of the revocation letter may qualify for retroactive reinstatement, but larger organizations and repeat offenders also need to show reasonable cause and file all the missing returns.13Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated The process runs months and costs money that filing on time would have saved.
Unrelated Business Income: A Second Return
Even a tax-exempt organization owes income tax on money earned from activities that don’t further its exempt purpose. Cross $1,000 in gross unrelated business income during the year and you must file Form 990-T and pay unrelated business income tax on the net profit.14Internal Revenue Service. Unrelated Business Income Tax Renting facilities to for-profit companies, selling newsletter advertising, and running a gift shop that sells items unrelated to the mission are common examples.
Form 990-T is separate from the annual 990-series return. You can owe it even if you’re otherwise exempt from filing Form 990. A church that clears $1,000 of unrelated business income has to file the 990-T even though it never files an information return. The tax is calculated at standard corporate rates, and estimated quarterly payments may be required if the liability is large enough.
Electronic Filing Is Required
Paper 990-series returns are no longer accepted. Under the Taxpayer First Act, Forms 990, 990-EZ, 990-PF, and 990-T all must be filed electronically through an IRS-authorized e-file provider using the Modernized e-File system.15Internal Revenue Service. E-File for Charities and Nonprofits Form 990-N has always been electronic-only, filed directly through the IRS website.
An authorized officer, typically the president, treasurer, or executive director, signs electronically. The e-file provider sends a confirmation, and the IRS either accepts the return or sends back a rejection listing what needs to be fixed. Most rejections come down to mismatched EINs or formatting issues and can be resubmitted quickly.
The Return Becomes a Public Document
Once accepted, a 990-series return is public. Tax-exempt organizations must make their annual returns available for inspection and provide copies on request, and returns must remain available for three years starting from the due date (including extensions) or the actual filing date, whichever is later.16Internal Revenue Service. Public Disclosure and Availability of Exempt Organization Returns and Applications: Public Disclosure Overview In practice, third-party aggregators keep them online far longer.
Not providing a copy on request costs $20 per day the failure continues, capped at $10,000 per return, and a willful refusal adds another $5,000.17Internal Revenue Service. Political Organization Filing Requirements: Penalties for Failing to Make Forms 990 Publicly Available Posting the return on the organization’s own website or through a public database satisfies the requirement and takes the individual request problem off the table.
For most filers, contributor names and addresses reported on Schedule B are not public information. Only private foundations and political organizations have to disclose that piece of the return.18Internal Revenue Service. Instructions for Schedule B (Form 990)
State Filings Are Separate
Filing with the IRS covers only the federal side. Most states require charities that solicit contributions from the public to register with the state attorney general or secretary of state before fundraising, and those registrations are typically renewed each year with their own fees. Religious organizations, educational institutions, and some small nonprofits are often exempt from state registration, but the exemptions vary from state to state.
Many states also require a separate annual report with the secretary of state to keep the organization in good standing as a legal entity, independent of any charitable solicitation registration. Letting a state filing lapse can bring fines, loss of the right to solicit donations, or administrative dissolution. Organizations that fundraise across state lines need to check the rules in every state where they actively solicit.
